Cannot save zone. Country United Kingdom must have at least one province associated

[jackhammerheart]

Hi there.  Yesterday all my shipping zones and rates were A-OK and i went to do a test order. 

I was told that my store doesn't ship to the United Kingdom, did some troubleshooting and I am getting an error stating: 

"Cannot save zone. Country United Kingdom must have at least one province associated."

I started from scratch, deleted my rates and tried again but the same thing is happening.  It's a bit frustrating as we're wanting to go live!  

Can anyone help please?
